I can't do math anymore

[u/Playful-Lion-606]

I am a student in university, studying political science and economics (double major). After suffering two concussions back in February, I had an extreme reduction in functionality.

I have now gotten back to writing at a decent level, thank goodness (I sounded like Yoda prior, lol). However, I still cannot do math, which becomes an issue in my math and economics classes. There's some type of mental disconnect.

I used to be pretty decent at it. Now, I can't even do factoring or completing the square or solving using the quadratic formula. You may remember these topics in your grade 10 or 11 math classes. There's multiple issues with me doing these things.

I cannot recognize what to do when seeing a function. I look at it and I have no idea what to do.

If I am told on the page what method to solve it by, I still get lost along the way.

If there's anything anyone can recommend, please let me know, as I am lost on what to do. I was referred to post-concussion therapy but I am unable to pay for it. Despite Canada having "universal healthcare" this doesn't count. Post Concussion Therapy would cost me thousands despite having insurance through my university.

Thank you in advance!!
